Normal gummed paper tape are made in accordance with the German standards DIN 55476 page 1 and essentially made up of two strips of Kraft paper hot glued together (~70°C) upon the interposition of fibreglass threads: some positioned lengthwise and others in an “X” form with an angle of 37°.
The application of vegetable glue (starch gum, standard spreading) or animal glue (gelatine, spreading on request) on paper strips complete the tape.
Made of Havana Kraft paper or coloured on request, with different weights based on the type of tape to be obtained.
Made of Kraft paper with different weights based on the type of tape to be obtained and carefully spread with glue.
Fibreglass filaments of different consistencies and quantities based on the tape to be obtained. Threads less than 68 tex (1 tex = 1g/km) are not used so as to guarantee suitable resistance.
Vegetable glue (V) or animal glue (A) that with the correct humidification guarantees a rapid, secure and long-lasting grip of the tape on the clean, but not prepared, walls of the packaging. 25 to 27 g/m² of glue is applied (+ – 2g/m²) depending on the type of tape.
Available with animal glue (gelatine) on request, as well as those types that are normally produced with vegetable glues.
The tapes are normally supplied on 70 mm diameter cores for machinable reels and without cores for dispensers. The gummed side faces outwards.
If the tape is used in an environment with a temperature between 12°C and 17°C, hot water (35°C) should be used which improves the holding speed. Use normal water for humidification that is not too hard (< 30° French). Remove the minimum number of reels to be used from the package and conserve the remainder in a dry (50-60% R.H.) and temperate (10-30°C) location.
